+Tracker} from within Emacs.
+
+For instance, it defines the command @code{M-x debbugs-gnu} for listing bugs,
+and the command @code{M-x debbugs-gnu-search} for bug searching.  If you
+prefer the listing of bugs as TODO items of @code{org-mode}, you could use
+@code{M-x debbugs-org} and related commands.
+
+A minor mode @code{debbugs-browse-mode} let you browse URLs to the GNU Bug
+Tracker as well as bug identifiers prepared for @code{bug-reference-mode}.")
